| 4 | The Solar Upper Transition Region Imager(SUTRI)Onboard the SATech-01 Satellite显示文摘The Solar Upper Transition Region Imager(SUTRI)onboard the Space Advanced Technology demonstration satellite(SATech-01),which was launched to a Sun-synchronous orbit at a height of~500 km in 2022 July,aims to test the on-orbit performance of our newly developed Sc/Si multi-layer reflecting mirror and the 2k×2k EUV CMOS imaging camera and to take full-disk solar images at the Ne VII 46.5 nm spectral line with a filter width of~3 nm.SUTRI employs a Ritchey-Chrétien optical system with an aperture of 18 cm.The on-orbit observations show that SUTRI images have a field of view of~416×416 and a moderate spatial resolution of~8″without an image stabilization system.The normal cadence of SUTRI images is 30 s and the solar observation time is about16 hr each day because the earth eclipse time accounts for about 1/3 of SATech-01's orbit period.Approximately15 GB data is acquired each day and made available online after processing.SUTRI images are valuable as the Ne VII 46.5 nm line is formed at a temperature regime of~0.5 MK in the solar atmosphere,which has rarely been sampled by existing solar imagers.SUTRI observations will establish connections between structures in the lower solar atmosphere and corona,and advance our understanding of various types of solar activity such as flares,filament eruptions,coronal jets and coronal mass ejections. | Xianyong Bai Hui Tian Yuanyong Deng Zhanshan Wang Jianfeng Yang Xiaofeng Zhang Yonghe Zhang Runze Qi Nange Wang Yang Gao Jun Yu Chunling He Zhengxiang Shen Lun Shen Song Guo Zhenyong Hou Kaifan Ji Xingzi Bi Wei Duan Xiao Yang Jiaben Lin Ziyao Hu Qian Song Zihao Yang Yajie Chen Weidong Qiao Wei Ge Fu Li Lei Jin Jiawei He Xiaobo Chen Xiaocheng Zhu Junwang He Qi Shi Liu Liu Jinsong Li Dongxiao Xu Rui Liu Taijie Li Zhenggong Feng Yamin Wang Chengcheng Fan Shuo Liu Sifan Guo Zheng Sun Yuchuan Wu Haiyu Li Qi Yang Yuyang Ye Weichen Gu Jiali Wu Zhe Zhang Yue Yu Zeyi Ye Pengfeng Sheng Yifan Wang Wenbin Li Qiushi Huang Zhong Zhang | 2023 | Research in Astronomy and Astrophysics2023，23，6： | 1 |
| 5 | Experimental Investigation on Shock Wave Characteristics of Aluminized Explosives in Air Blast显示文摘To investigate the shock wave characteristics of RDX-based aluminized explosives,air blast tests were conducted for measuring the parameters of 10 kg aluminized explosives which contained 0-40% aluminum.The results showed that with the increasing of aluminum content,the overpressures and impulses increase at first and then decrease within 7 m or 5 m,which reached the maximum when aluminum content was 20% or 30%.Power exponential formulas are used to fit the shock wave parameters vs scaled distance,where an equal weight of TNT is used to calculate the scaled distance.The overpressures of HL0 and TNT in tested locations not only conform to the similar law,but also conform to the same attenuation law after gaining the scaled distances of equal TNT mass.The pre-exponential factors of overpressure and impulse,k_p and k_I,decrease along with the increasing of Al content and keep the same pace as the calculated P_(CJ).The attenuation coefficients a_P and aIincrease a_t first and decrease later with the increasing of aluminum content,and they reached the maximal values with30% Al containing,which keeps the same pace as the calculated Q_V. | Xiaoyu Duan Qingzhong Cui Xueyong Guo Qiushi Wang Qingjie Jiao | 2017 | Journal of Beijing Institute of Technology2017，26，2： | 1 |

| 7 | Therapeutic Effect and Mechanism of Caulophyllum robustum Maxim Extract on Adjuvant Arthritis Rats显示文摘[Objectives]To study the anti-inflammation and anti-swelling effect of Caulophyllum robustum Maxim( CRM) extract on secondary lesions of adjuvant arthritis( AA),associated inflammatory factors of AA rats and mice immune function. [Methods]Rats were divided into high,middle and low dose CRM extract groups( 69. 23,34. 61,17. 31 mg/kg),methotrexate group( 0. 68 mg/kg),triptolide group( 7. 88 mg/kg),model group and normal control group. The AA rat model was induced by intradermal injection of Freund's complete adjuvant( FCA). After the AA model was established successfully,the paw swelling of AA rats was observed and recorded. The levels of interleukin-1β( IL-1β),interleukin-4( IL-4),interleukin-10( IL-10),Tumor Necrosis Factor-α( TNF-α),interleukin 17( IL-17),interferon( IFN-γ),granulocyte colony-stimulating factor( G-CSF) and transforming growth factor( TGF-β) in the serum of AA rats were detected by enzyme-linked immunosorbent assay( ELISA). The spleen was removed and weighed for detecting the drug influence on the immune organs.Impacts were observed by gavage administration at different dosages of 25 mg/kg,50 mg/kg,100 mg/kg for seven days,adopting carbon granules clearance test,delayed-type hypersensitivity induced by dinitrofluorobenzene( DNFB) coupled with flow cytometry evaluating lymphocytes( CD3^+,CD4^+,CD8^+) activation and serolysin test. [Results] Compared with the model group,the joint swelling,spleen index and inflammatory cytokines( IL-1β,IL-4,IL-10,TNF-α,IL-17,IFN-γ,G-CSF,TGF-β) were reduced significantly( P < 0. 05,P < 0. 01). And the activity of CRM was significantly superior to methotrexate and triptergium. Moreover,the results indicated that different dosages of 25 mg/kg,50 mg/kg,100 mg/kg of CRM could significantly reduce the carbon granules clearance index( K) and phagocytic index( a),inhibit the phagocytosis of mononuclear macrophages,reduce the mice swelling extent and inhibit DTH in mice induced by DNFB,decrease the quantity of serum hemolysin. Percentage of CD3^+,CD4^+,and the ratio of CD4^+,CD8^+ notably decreased,whereas CD8^+ obviously increased. Intragastrica dose of 50 mg/kg,100 mg/kg were acknowledged as more objective inhibiting effect compared with a dosage of 25 mg/kg.[Conclusions] Decreasing inflammatory cytokines content,non-specific immune,humoral immune and cellular immune function may be the therapeutic mechanism for rheumatoid arthritis( RA). | Shaowa LU Hong SU Fengming YU Qiushi WANG Yuyan GUO Guoyu LI Haixue KUANG | 2018 | Medicinal Plant2018，9，1： | 1 |

| 10 | Converting intercalation-type cathode in spent lithium-ion batteries into conversion-type cathode显示文摘The widespread applications of lithium-ion batteries(LIBs)generate tons of spent LIBs.Therefore,recycling LIBs is of paramount importance in protecting the environment and saving the resources.Current commercialized LIBs mostly adopt layered oxides such as LiCoO_(2)(LCO)or LiNi_(x)Co_(y)Mn_(1-x-y)O_(2)(NMC)as the cathode materials.Converting the intercalation-type spent oxides into conversion-type cathodes(such as metal fluorides(MFs))offers a valid recycling strategy and provides substantially improved energy densities for LIBs.Herein,two typical Co-based cathodes,LCO and LiNi_(0.6)Co_(0.2)Mn_(0.2)O_(2)(NMC622),in spent LIBs were successfully converted to CoF_(2) and(Ni_(x)Co_(y)Mn_(z))F_(2) cathodes by a reduction and fluorination technique.The as converted CoF_(2) and(Ni_(x)Co_(y)Mn_(z))F_(2) delivered cell energy densities of 650 and 700 Wh/kg,respectively.Advanced atomic-level electron microscopy revealed that the used LCO and NMC622 were converted to highly phase pure Co metal and Ni_(0.6)Co_(0.2)Mn_(0.2) alloys in the used graphite-assisted reduction roasting,simultaneously producing the important product of Li_(2)CO_(3) using only environment friendly solvent.Our study provided a versatile strategy to convert the intercalation-type Co-based cathode in the spent LIBs into conversion-type MFs cathodes,which offers a new avenue to recycle the spent LIBs and substantially increase the energy densities of next generation LIBs. | Dingding Zhu Yong Su Jingzhao Chen Xiangze Ou Xuedong Zhang Wen Xie Yuyan Zhou Yunna Guo Qiushi Dai Peng Jia Jitong Yan Lin Geng Baiyu Guo Liqiang Zhang Yongfu Tang Qiao Huang Jianyu Huang | 2024 | Nano Research2024，17，5： | 0 |
| 11 | Revealing alkali metal ions transport mechanism in the atomic channels of Au@a-MnO_(2)显示文摘Understanding alkali metal ions’(e.g.,Li^(+)/Na^(+)/K^(+))transport mechanism is challenging but critical to improving the performance of alkali metal batteries.Herein using a-MnO_(2)nanowires as cathodes,the transport kinetics of Li^(+)/Na^(+)/K^(+)in the 2×2 channels of a-MnO_(2)with a growth direction of[001]is revealed.We show that ion radius plays a decisive role in determining the ion transport and electrochemistry.Regardless of the ion radii,Li^(+)/Na^(+)/K^(+)can all go through the 2×2 channels of a-MnO_(2),generating large stress and causing channel merging or opening.However,smaller ions such as Li^(+)and Na^(+)cannot only transport along the[001]direction but also migrate along the<110>direction to the nanowire surface;for large ion such as K^(+),diffusion along the<110>direction is prohibited.The different ion transport behavior has grand consequences in the electrochemistry of metal oxygen batteries(MOBs).For Li-O_(2)battery,Li^(+)transports uniformly to the nanowire surface,forming a uniform layer of oxide;Na^(+)also transports to the nanowire surface but may be clogged locally due to its larger radius,therefore sporadic pearl-like oxides form on the nanowire surface;K^(+)cannot transport to the nanowire surface due to its large radius,instead,it breaks the nanowire locally,causing local deposition of potassium oxides.The study provides atomic scale understanding of the alkali metal ion transport mechanism which may be harnessed to improve the performance of MOBs. | Jingzhao Chen Yong Su Hongjun Ye Yushu Tang Jitong Yan Zhiying Gao Dingding Zhu Jingming Yao Xuedong Zhang Tingting Yang Baiyu Guo Hui Li Qiushi Dai Yali Liang Jun Ma Bo Wang Haiming Sun Qiunan Liu Jing Wang Congcong Du Liqiang Zhang Yongfu Tang Jianyu Huang | 2023 | Journal of Energy Chemistry2023，，7： | 0 |
| 12 | In situ Observation of Li Deposition-Induced Cracking in Garnet Solid Electrolytes显示文摘Lithium(Li)penetration through solid electrolytes(SEs)induces short circuits in Li solid-state batteries(SSBs),which is a critical issue that hinders the development of high energy density SSBs.While cracking in ceramic SEs has been often shown to accompany Li penetration,the interplay between Li deposition and cracking remains elusive.Here,we constructed a mesoscale SSB inside a focused ion beam-scanning electron microscope(FIB-SEM)for in situ observation of Li deposition-induced cracking in SEs at nanometer resolution.Our results revealed that Li propagated predominantly along transgranular cracks in a garnet Li_(6.4)La_(3)Zr_(1.4)Ta_(0.6)O_(12)(LLZTO).Cracks appeared to initiate from the interior of LLZTO beneath the electrode surface and then propagated by curving toward the LLZTO surface.The resulting bowl-shaped cracks resemble those from hydraulic fracture caused by high fluid pressure on the surface of internal cracks,suggesting that the Li deposition-induced pressure is the major driving force of crack initiation and propagation.The high pressure generated by Li deposition is further supported by in situ observation of the flow of filled Li between the crack flanks,causing crack widening and propagation.This work unveils the dynamic interplay between Li deposition and cracking in SEs and provides insight into the mitigation of Li dendrite penetration in SSBs. | Jun Zhao Yongfu Tang Qiushi Dai Congcong Du Yin Zhang Dingchuan Xue Tianwu Chen Jingzhao Chen Bo Wang Jingming Yao Ning Zhao Yanshuai Li Shuman Xia Xiangxin Guo Stephen J.Harris Liqiang Zhang Sulin Zhang Ting Zhu Jianyu Huang | 2022 | Energy & Environmental Materials2022，5，2： | 0 |
| 13 | Genomic,transcriptomic,and epigenomic analysis of a medicinal snake,Bungarus multicinctus,to provides insights into the origin of Elapidae neurotoxins显示文摘The many-banded krait,Bungarus multicinctus,has been recorded as the animal resource of JinQianBaiHuaShe in the Chinese Pharmacopoeia.Characterization of its venoms classified chief phyla of modern animal neurotoxins.However,the evolutionary origin and diversification of its neurotoxins as well as biosynthesis of its active compounds remain largely unknown due to the lack of its high-quality genome.Here,we present the 1.58 Gbp genome of B.multicinctus assembled into 18 chromosomes with contig/scaffold N50 of 7.53 Mbp/149.8 Mbp.Major bungarotoxin-coding genes were clustered within genome by family and found to be associated with ancient local duplications.The truncation of glycosylphosphatidylinositol anchor in the 3'-terminal of a LY6E paralog released modern three-finger toxins(3FTxs)from membrane tethering before the Colubroidea divergence.Subsequent expansion and mutations diversified and recruited these 3FTxs.After the cobra/krait divergence,the modern unit-B ofβ-bungarotoxin emerged with an extra cysteine residue.A subsequent point substitution in unit-A enabled theβ-bungarotoxin covalent linkage.The B.multicinctus gene expression,chromatin topological organization,and histone modification characteristics were featured by transcriptome,proteome,chromatin conformation capture sequencing,and ChIP-seq.The results highlighted that venom production was under a sophisticated regulation.Our findings provide new insights into snake neurotoxin research,meanwhile will facilitate antivenom development,toxin-driven drug discovery and the quality control of JinQianBaiHuaShe. | Jiang Xu Shuai Guo Xianmei Yin Mingqian Li He Su Xuejiao Liao Qiushi Li Liang Le Shiyu Chen Baosheng Liao Haoyu Hu Juan Lei Yingjie Zhu Xiaohui Qiu Lu Luo Jun Chen Ruiyang Cheng Zhenzhan Chang Han Zhang Nicholas Chieh Wu Yiming Guo Dianyun Hou Jin Pei Jihai Gao Yan Hua Zhihai Huang Shilin Chen | 2023 | Acta Pharmaceutica Sinica B2023，13，5： | 0 |
